Service indicator

System that informs the driver when the
next service is due, in accordance with the
manufacturer's service schedule.
The point at which the service is due
is calculated from the last service
indicator zero reset, according to the distance
covered and the time elapsed since the last
service.
For BlueHDi Diesel versions, the level of
deterioration of the engine oil may also be
taken into account, depending on the country
of sale.

More than 1800 miles (3000 km)
remain before the next service is due

When the ignition is switched on, no service information
appears in the instrument panel central screen.

Between 600 miles (1 000 km)
and 1800 miles (3 000 km) remain

For a few seconds after the ignition is switched
on, the spanner symbolising the service
operations comes on. The distance recorder
display line or a specific message in the
instrument panel central screen indicates the
distance remaining before the next service is due.

on, the screen indicates:

A few seconds after the ignition is switched on,
the spanner goes off

; the distance recorder

resumes its normal operation. The screen then
indicates the total and trip distances.

A few seconds after the ignition is switched
